To all whom it -may co'ncern.-

Be it known that I, J OHN D'. REED, of York, in the countyYork' and State of Nebraska, have invented anew and Improved Electro-Magnetic Gar-Unco'u'pler', of which the {ollowing isa full, clear, and exact descrip- 1on. l .The object of my invention is to provide a new and improved device for uncoupling cars by electricity, whereby any desired car can be uncoupled bya person on the locomotive. f f The invention consists in a caruncoupling device adapted to be operated by electricity. The invention further consists in the combi-' nation, with a car, of a pivoted shackle onthe draw-head, an electro-magnet for operating the shackle, conductors for conducting the electricity to the electro magnets, contactstrips on the ends of the cars for uniting the conductorsof. the several cars, and in numerone parts and details and combinationsof the same, as will be fully set forth and described hereinafter.

Reference is to be had to. the accompanying drawings, forming part. of this specification, in which similar letters of referenei ndicate cor,- responding parts in all the figures; p, Figure 1 isa plan view of the end parts of the underside of two cars provided with my improved eleotro magnetic car uncoupler, the cars being shown coupled. Fig. 2 is a side view of the same, parts being shown in I s ections.- Fig. 3 is aside view of a modified construction.- Fig. 4 is a plan view of the un-' der side of the same Fig. 5 is a plan view of theunder side of a train-of .cars pirovided with my improved electromagnetic unc'oifphre The, draw-head A, held on the under side of the car, is held toslide in the direction of the length of the car in'suitable guides, the drawhead being pushed toward the end of, the car by; a bufl'er-springfA', acting on the draw-' head inthe usual manner. Thedraw-head is provided at its free end ,with a hook,-AF. To

-5 the draw-head a laterally-projecting arm, 1 3,

is fastened, to which an electro-magnet, 0-, 1s secured. A; Uf-shaped frame, 1), is ivoted, ,on'the top and hottomlsurface' of t e draw- -head to swing in thehorizontal plane, the said shaped frame or shackle D being provided with a vertical enlargeitnent' or loop, D, at its shackle toward the side v with arectangular arm, F,

'iugs :contain spiral springs L, held between distance from free end, so that cars can be coupled on which I the 'draw -heads are at diflerent elevations abovethe ground: Springsaresecured to the shackle and draw-head and draw the 'edgeof the draw-head. The shackle D is provided at its inner end forming the armature of the electro-magnet' G. If desired, the outer end 'of the ,arm F can -.be "pivoted to a short connecting rod, G, pivotedto an armature, F, as shown in the modification on the right-hand side of Figs. 1 and 2.

Above each draw head A a transverse bar, J, is held parallel with and a-short distance from the. end of the car, from which. bar la .series of rods, K, project toward the car and i are held to slide in tubular or likeeasings L, projecting from the endfof the car, which casthe ends of' the casing, and a. cross-piece or block, on the rod, and thus serve as buffers, and at all times hold the bars J the same the ends of the car. -From'th'e bar J a series, of contact strips or tongues, M, project outward parallel with the longitudinal axis of the car, which tongues are provided with upright parts -lVL-, so as to ini sure acofitactdfthetongueswhen thecars are thetongues are at slightly dif jolted or when ferent elevations above the ground. The 'conducting-wires a, secured to the bottoms of the car, have their ends secured to theinner ends of the tongues M. If desired, the tongues can be formed of two strips, N, placed edgewise and having upright parts N at the ends to insure contactat all I times, as stated above. The

strips are arranged V-'shaped, one being longefthan thebther, so that the ends of, the strips on one bar J can pass between the ends of the strips N on the bar J of the'other car, as shown in the lowerpart'of Fig. 1. The tongues M and strip s N ,are made oil-spring material, so that they'willberpressed against each other andwill always. remain incontact. 5 The wires a are secured to the under side of the bottom of the ear ystaples or otherwise,

and the said wires or conductors are insulated.

Each car-is provided. with one more wire than i there are cars in theitrain'. For instance, an a .car having eight wires can be coupled on any train of seven carsor less, or cars hav ng five Each car is provided at each .e contact-ton m The tender 0 is The said buttons are'marked d d! 50 tton d or wire a y wire h.

wires can be coupled on a train offourcars or less, and a car having twenty-one wires canbe coupled on a train of twent cars or less, Ste. ndwith as many gues aslthere are wires a plus two. Fori'n stance, a car having eight wires must have ten contact tonguesat each end. In Fig. 5 the tender and only-three cars and a part of a fourth of a train of seven cars are shown provided with'a switch-lever, P, a battery, Q, connected bya wire, b, with the pivoted end of the lever 1 and. withone. of a series of contactrbuttons, of which there are as many as thereare wires (1 plus; one. d d 'd, &c.', and, connected by 'wire's'g g g" 9*, & with the "corresponding tongues M. The magnet O of the tender is connected to one of the tongues M by the wire I and to the contact end of the car the magnet 015 connected by'a wire, h, with theseco'nd tongue. The other end of the. magnet G is connected by a wire, 1, with the corresponding tongue. At the rear I are the same e, a, and the are only used as return wires, used when thebattery is to the when the battery is to thehesecond wire,a?,extends from the third tongue M at the front to the second tongue at the rear, The third wire, ai, extends from the fourthtongue M atthe front to thethird tongue-at the rear. The fourth extends, from thesixth tongue at the ongue at the rear, and so on, as shown." If moreoriless conductors and more or less tongues are arranged on the car, the connections willbemad e correspondingly ove. The tongues, which are connected to the electro-magnetsby wires l Z, a're shown inEig. 5 to one side of the center of the ca'r; but in practice they willbe in the centerto permit perfect connection bearrying the bat-- nd of the train: :nwhenthe cars l e-shackles D are i of the opposite drawas at.- the tenders;v The firstw ir eighth wire, a, the wire a being left, and the wire-a tery beat the front or'rear e Theoperation'is as follows are coupled, the loops D of t If a caris to .be nnc'ou ing. circuit, is closed sp'onding'fmagnets G," which magnets attract. their armature's, and thereby swing the free e'shackles in the directionsof the I y disengaging the shackles f th e 'drawsheads, and thus theears.'
